C# - Setting Hidden Input Value In JavaScript, Then Accessing It In Codebehind
Apr 21, 2010
I have been trying to set the value of a hidden input by using Javascript and then access the value from within my C# codebehind. When I run the code that is copied below, the value that is assigned to assignedIDs is "", which I assume is the default value for a hidden input. If I manually set the value in the html tag, then assignedIDs is set to that value.
This behavior suggests to me that the value of the input is being reset (re-rendered?) between the onClientClick and onClick events firing.
html/javascript:

I have static html paypal buynow button that works great, but it's static.
[Code]....
But it is possible to change the values for the hidden inputs from .net codebehind code? I found this post which takes a different approach of sending these hidden fields instead as a query string to paypal. Not sure I like that though as would this not possiby explose some of those fields like the return page?
http://www.makaistudio.com/mksBlog/post/ASPNet-and-Paypal-buy-now-button-Offer-discount-at-checkout-in-code-behind.aspx
Basically what id like to do change the important parts of the button and info I'm sending to make it dynamic.I know I can do something like this in the markup, but that would mean having to fetch data mulitple times was hoping I could somehow adderss the field values directly in the codebehind. Or possibly dynaically generate and insert the entire changing input type fields from the codebehind
<input type="hidden" name="invoice" value="<%= getinvoice()%>">
Possible to add them with something like this: myform.Attirbutes.Add (???). If so how do I contruct these input types in .net?As far as return logic security, I've tested that it's solid, i just need to automate the button process so I don't have to create a buy now page and button for each product.

I am trying to set a hidden type value to x on Server Side and then access it with Javascript. I have tried multiple ways to accomplish this.
At the basic level this is what I am trying to do.
Aspx page
<asp:HiddenField ID="HidRowNumber" runat="server" />
CS Page
In IsPostBack
HidRowNumber.Value = EFileRowNumber.Text;
Javscript
var status = document.getElementById("<%= HidRowNumber.ClientID %>").value;
When I am debugin it say it HidRowNumber's Value has changed to x but when I access the value with JS it always returns ''.

I have a user control that i have registered to an aspx page. Now from the aspx page, i am trying to access one of the registered usercontrol's hiddenfield value in my aspx page using javacript using the below code:
tst = document.getElementById('control1$hdnField').value;
I looked into the page's trace, and i could see 'control1$hdnField'. Then why i am not getting its value in my aspx page. I have also confirmed that the hidden field by this name exists in the user control and also has a default value set.

I'm evaluating two options of accessing a server side data on client side. Little bit confused about the efficiency or may be you can call it as finding best approach to do it.
I need to access a server side data may be an integer value in javascript on client side. I know about two options to do it.Create a public variable or property on server side and set it to javascript variable on client side as below:
var value = eval(<% =value %>);
Create a asp hidden variable and set value in this hidden variable from server side and access it through javascript using document.getElementById().
Which is the best approach and what are the pros and cons?

In order to use hidden input, does the hidden input must be inside a form?
Is there any strategy to perpetuate the hidden input value between requests? So far I guess it's through query string / URL?

I have an input...
<input
id="ratingField"
runat="server"
type="hidden"
/>
this hidden input is used by a star rating control. the user gives a star rating of 1 to 10 by clicking on the stars and some javascript detects which star was clicked and fills the input with the corresponding number.
I want to use a RequiredFieldValidator to ensure that the client has selected a star and if not return an error message to my validation summary.but the validator seems to be throwing an exception. How do I do this?

This is probably embarrassingly easy, but I've having problems getting this to work.
On ResidentAddress.aspx, I have 2 user controls (AppName.ascx and NavButtons.ascx). When a textbox in AppName.ascx has focus, I want to update a hidden input field on NavButtons.ascx with the value of "TRUE". In the codebehind page for NavButtons, I want to see what the value of this hidden input filed is.
This is what I have so far:
NavButtons.ascx
<input type="hidden" id="IpChangeFlag" name="ChangeFlag" runat="server" value="FALSE" />
AppName.ascx
<asp:TextBox ID="txtFirstName" runat="server" onFocus="document.getElementsByName('ChangeFlag').value='TRUE';">
NavButtons.ascx.vb
If IpChangeMade.Value.Trim.ToUpper = "TRUE" Then
MyValue = true
End If
I am unable to change the value of ipChangeFlad. It always has the value of FALSE.

I'm using jQuery to build an IFRAME and pass some hidden input values to a Download.aspx page - jQuery code looks like this
Code:
$('<form action="'+ url +'" method="'+ (method||'post') + '" target="iframeX">'+inputs+'</form>')
.appendTo('body').submit().remove();
The inputs variable looks like this
<input type="hidden" name="filename" value="mit-license.txt" />
And the top of the Download.aspx code behind looks like this
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim ctx As HttpContext = HttpContext.Current
Dim response As HttpResponse = ctx.Response
Dim sFile As String = "mit-license.txt" ' Request.QueryString("filename").ToString
[Code] ....
I could not find the INPUT value - where does it pass in? I checked the "sender" and the ctx objects and could not find it... I hardwired the mit-license.txt filename to prove that the download works...

I have an ASP.NET application designed for a Windows CE device that needs to take in information from a scanned barcode. The device sends the scanned data as string input with a crlf to whatever field has focus. I set up my page with a textbox that takes the input and posts back to look up the item.
Now, I'd like that box to not be visible to the user, but IE complains when I set focus to it if the field is "visibility: hidden" or "display: none". I've tried moving it off screen using absolute coordinates, but setting the focus scrolls the window to the new location.

Possible Duplicate: asp.net mvc: why is Html.CheckBox generating an additional hidden input
I'm rendering a checkbox in an asp.net mvc app, and the control is also outputting a hidden field like this:
<input id="blah-64" name="blah-64" value="true" type="checkbox">
<input name="blah-64" value="false" type="hidden">
Problem is, when I post the form, the form key "blah-64 returns "on, off".
Why is this?

From the master page of my ASP.NET site I need to set the value of a hidden field in every get and post request and then subsequently read it in the next request.The problem is that in the post request the code works fine but when the client sends a get request I am unable to read the value of the hidden field from teh Master Page. Is the hidden field the proper approach to this and if so how do I read the value set in the hidden field in the subsequent get request. If the hidden field is not the proper approach for this then what else should I use?

I am trying to set the width and height of images in a datalist in the codebehind.
The plan is to do something more complex than this based on the width/height, so setting width and height in the aspx file to 50% is not an option.
For some reason I always get 0 for width and height. Image1.ImageUrl is what i would expect though. Image is the System.Web.UI.Webcontrols.Image, not a System.Drawing.Image.

I'm using V.S. 2008 and asp.net MVC. I have a form in this page that user selects various items from Select controls. I then construct a string varible that contains each selected element's id a hidden input control that holds this information. How can I pass this variable (and it value of course) to a Controller Action? I am using regular Html Form and the Submit button.
In the following code you see the "ResearchInterests" is the one that holds the string but I can't even reference it in my Controller action, Search. How can I correct this?

I want to create input inside gridview, the id of the input is set by me. I do want to use HiddenField control because when generating the id of the control, it will set id to gridview_ctrl.....
The input looks like this: <input id="myid01" value="myvalue" type="hidden">. Note that id is generate by me in the code behind.
